EDEN PRAIRIE, Minn. -- Adrian Peterson returned to the field as the Minnesota Vikings wrapped their practice week on Friday, and coach Leslie Frazier downplayed the possibility the NFL's leading rusher may be limited this weekend because of his sore abdomen.

"He feels pretty good, feels better than he did (last) Friday this time," Frazier said. "So, I don't think we have to go into it thinking about limiting his carries or anything like that. I think we go full-speed ahead. That's what he wants. That's what our doctors are telling me. He's ready to go."

Peterson had sat out the previous two days to rest the sore abdomen that sent him to the sideline late in last weekend's victory at Houston. But Frazier has said all week the team was just being cautious in advance of Sunday's critical finale against Green Bay.

"Adrian was able to get some work, so that was a positive for us," Frazier said. "He moved around very well. So, looking forward to having him out there on Sunday."

Cornerback Antoine Winfield (knee/hand) didn't practice either and was listed as questionable (50% chance of playing). But Frazier said the Vikings believe he's "going to be fine" to play one week after breaking a bone in his right hand.

"We're going to wrap it and they're going to have a protective padding over it," Frazier said. "So, that's going to help him. But he showed me (Friday) that he can grip with it. I feel like he'll be able to tackle, do what he has to do."

Left end Brian Robison (shoulder) also was listed as questionable after having limited participation for a third consecutive day. But Robison said he intends to play through the pain, given the magnitude of a game that would send the Vikings to the playoffs with a win.

"I really want to get inside and just talk with him a little bit and just see how he felt," Frazier said. "We put him through some more things (Friday) and had Brendan Daly, our d-line coach, take him through a little bit more."

The Packers ruled out defensive back Charles Woodson (collarbone) on Wednesday and also ruled out halfback James Stark (knee) on Frriday. Cornerback Davon House (shoulder/hip) is doubtful (25% chance of playing) and receiver Randall Cobb (ankle/knee) is questionable.
